Overview
The TB62747AFNAG,EL is a 16-output constant current LED driver IC fabricated using Bi-CMOS technology. It integrates shift registers, latches, AND gates, and regulated current sources for high-speed data transmission. The device operates with power supply voltages (VDD) ranging from 3.0 V to 5.5 V. It supports an output voltage up to 26 V and provides adjustable output currents, typically reaching 45 mA at 5.0 V supply. The component is housed in a 24-pin SSOP package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates 16 channels of shift registers, latches, AND gates, and constant-current outputs for efficient LED panel display control.
- Utilizes Bi-CMOS process technology to satisfy system requirements for high-speed data transmission.
- Provides regulated constant current outputs adjustable via a single external resistor.
Applications
- LED lighting systems
- LED panel displays
- High-speed data transmission interfaces
Procurement Notes
Verify the specific suffix 'AFNAG' against official Toshiba Semiconductor and Storage documentation to confirm pinout and electrical characteristics, as variations exist within the TB62747 series. Ensure compatibility with the required 24-SSOP footprint and check for RoHS compliance status in the latest datasheet revision before finalizing procurement.
Selection Notes
Select this component when designing LED drivers requiring 16 independent constant current channels controlled via serial data input. It is suitable for applications needing adjustable current settings between 1.5 mA and 45 mA depending on the supply voltage. Consider the 26 V maximum output voltage limit and the 24-SSOP package constraints for PCB layout.
Part Context
This part belongs to the TB62747 series of 16-output constant current LED drivers. The series includes variants such as TB62747AFG, TB62747AFNG, and TB62747BFNAG, all designed for LED and LED panel display applications using Bi-CMOS silicon monolithic technology.
Replacement Considerations
Official substitutes within the same family include TB62747AFG, TB62747AFNG, and TB62747BFNAG. Verify functional equivalence and package compatibility before substitution.
